Water cooling system:
Cooling water jackets are provided around the cylinder, cylinder head, valve seats etc. The water when circulated through the jackets, it absorbs heat of combustion. This hot water will then be cooling in the radiator partially by a fan and partially by the flow developed by the forward motion of the vehicle. The cooled water is again recirculated through the water jackets.
Antifreeze mixture
In western countries if the water used in the radiator freezes because of cold climates, then ice formed has more volume and produces cracks in the cylinder blocks, pipes, and radiator. So, to prevent freezing antifreeze mixtures or solutions are added in the cooling water.
Normally following are used as antifreeze solutions:
(i) Methyl, ethyl and isopropyl alcohols
(ii) A solution of alcohol and water
(iii) Ethylene Glycol raises the boiling temperature substantially and hence more heat dissipation
(iv) A solution of water and Ethylene Glycol
(v) Glycerin along with water, etc.
(vi) Chromates are used to prevents deposit
Water cooling system mainly consists of:
-Radiator
-Thermostat valve
-Water pump
-Fan
-Water Jackets
-Antifreeze mixtures
Various types of water cooling systems are given as;
(a) Thermo-syphon cooling
(b) Forced or pump cooling
(c) Cooling with thermostatic regulator
(d) Pressurised water cooling system
(e) Evaporative cooling
